DRIVER FOR ANCHOR-PLATES.

To all whom t may concern: p 1.

Be 1t known that I, WILLIAM L.v HAAG, a citizen of the United States ofAmerica, re-

7'siding at'Lansing, in the county of Ingham to firmly engage the earthand prevent its being pulled out by heavy strain put upon the stay.

It is also an object-of the invention to provide suitable means forpositioning the anchor which means may be-driven into the ground withthev anchor held thereonland may then be pulled out leaving the anchorembedded in the earth at the desired depth. A further object of theinvention is to provide certainV new and useful features in theconstruction of the anchor and driver, all as hereinafter more fullydescribed.

To these ends the invention consists in the matters hereinafter setforth and more particularly pointed o ut in the appended claims,referencebeing had tothe accompanying drawing in which;

Figure l is a side elevation of a driver with an anchor in section inplace thereon illustrating the manner in which they are driven into theground; Fig. 2 isa similar view with the driver removed; Fig. 3 is adetail illustrating the position of the anchor 'in use; Fig. 4 is anelevation of the driver with the anchor in place thereon; Fig. 5 is atransverse section of Fig. l on the line y-Jy; Fig. 6 is a kperspectiveview of the anchor detached; Fig. 7 is a perspective view illustratingmeans for pulling the driver from the ground; and Fig. Seis an enlargedde'- Y tail of the upper end of the driver bar and pinch ring thereon.

In providing anchors for the stay wires of telephones, telegraph poles,buildings and other structures it has been the common practice to dig ahole in the ground, place lthe anchor with the wire or cable attachedthereto in the bottom of the hole and then fill up ythe hole, but in solpositioning the( ground unless a great deal of care is takenVvSpecification of Letters Patent. Patented Apr. 1.3, 1915. lApplication flied rune 21,1913. seriaiNa'rf/'Sae f l' "6o anchor 1sliable to be pulled out ,of` the to tamp the ground down in the holeand., y

in many instances it is necessary to weight the` anchor vby placingVstone or other heavy articles thereon within the hole.

In applicants construction a yplate l of' suitable size/and form isdriven into the ground edgewise lbymeans of a suitable driver comprisinga bar 2 which is 'suitably formed at its lower end to engage and holdthe plate while said plate is being driven into the" ground by means ofthe driver. Thisplate is preferably substantially rec'- ta'ngular inforni andjis concave at its lower side and convex at its uppery side.with ax center hole 13 through which the stay wire or cable 3 is passedand made fast to the i plate by forming a knot on the end of the wire atthe under or concave side `of the` plate. The bar 2 is'forrned with aflattened lower end portion lhaving a pointed end 5 so that it may bedriven into the ground easily and the fiat upper side of this lower endVportion forms av seat for the anchorV plate, said plate resting thereonat two'kdia'l'- metr'ically opposite corners'which corners arepreferably cut away to vform a straight edge to engage the seat. At thepoint where the bar 2 merges into the flattened end portion, said bar isformed with an undercutl groove 6 to receive the ,edge of the plate,said groove formingk a firm seat lfor the plate so that ywhen the bar isdriven into the ground with the plate engaged therewith,

said plate will be forced edgewise into the l earth. To hold the plateagainst vlateral movement uponvits seat on the flat side of the bar, alug'7 is formed on the bar to en- Y gage a slot 8 in the plat e,',theupper side of the lug being tapered or cut away so that it willreadilywithdraw from the slot when the bar or driveris pulled 'out oftheground by means of a pinch ring 9 which slides freely upon its upper endand is adapted to tilt thereon and grip the bar when it is actuated by`means of a suitable l pry or lever 10 placed through an Vopening in anear ll on thev ring.

After the driver with the anchor plate in place thereon has been rdriveninto the ground as shown in l, and the driver has been removed as shownin Fig. 2, when a strain is put upon the stay wire 3, the tendency ofthe anchor plate will be to turn within the ground to a position atright angles to the direction of strain upon the stay wire by reason ofthe attachment of the wire to the center' of the plate at one sidethereof and the concavo-convex form of the plate. The two laterallyextending corners of the plate which project at right angles to the lineof strain upon the stay wire also tend to cause the plate to turn in theground and if found desirable the plate may be provided with springfingers l2 which are secured to the under concave side of the plate andcurved outwardly and laterally therefrom at each side of the driver andextend beyond the upper edge of the plate. These spring fingers offer nomaterial resistance to the driving of the plate into the ground as theywill straighten out as they come into engagement with the earth, butafter the driver has been removed and a strain is put upon the staywire, these lingers curving voutwardly away from the plate in thedirection of the line of pull upon the stay wire, will dig into theearth at 'the upper edge of the plate thus oliering an additionalresistance at that edge to the pulling of the plate from the ground. Theturning of the plate within the ground is therefore made positive by theuse of these fingers.

By driving the anchor plate into the ground edgewise the earth isdisturbed but slightly and after the plate has turned within the groundby pulling upon the stay wire it will have a firm hold upon portions ofthe ground which are in their natural condition. An anchor plate ofsmall dimensions may, therefore, be used and the driving of theV plateinto the ground greatly facilitates the anchoring of it. Obviously theanchor plate vmay be made of any desired sizeand form with the springfingers attached thereto or a plain plate used, as desired. The driver'may also have other forms than that shown and other changes mayobviously be made in the construction and arrangement of parts withoutdeparting from the spirit of the invention and I therefore do not limitmyself to the form or arrangement shown.

Having thus fully described my invention what I claim is :d

l. A driver for an anchor plate, comprising a bar having a flattenedlower end portion to accommodate a plate, said flattened lower endportion being cut away to provide opposed seats for the lower end ofsaid plate, said iiattened lower end portion having the upper endthereof undercut to provide a groove to receive theupper end of saidplate, and a lug on the fiattened lower end portion of said bar adaptedto engage the plate.

2. A driver for an anchor plate, comprising a bar having a flattenedlower end portion terminating in a point, said flattened lower endportion adapted to accommodate a plate and provide a seat for the lowerend thereof, said bar at a point where it merges into the flattened endportion having an undercut groove to accommodate the upper end of saidanchor plate, and a` lug on the flattened lower end portion of said baradapted to engage in said plate, said lug having the upper end thereoftapered whereby it can be readily withdrawn from the plate.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM L. HAAG.
